Abstract
The utility model relates to a machine part specifically provides a flywheel, including the flywheel body, the flywheel body includes flywheel inner ring, flywheel outer loop and sets up the ring gear in the flywheel outer loop outside, the flywheel inner ring passes through the connecting rod with the flywheel outer loop and is connected, the endocyclic center of flywheel is provided with the dead eye, be provided with the location pinhole on the circumference that flywheel outer loop and ring gear meet, the location pinhole is including setting up the half first pinhole and second half pinhole of setting on the ring gear on the flywheel outer loop. The utility model provides a flywheel, simple structure, the outside of erroneous tendency flywheel body because the quality of flywheel body distributes for the flywheel main part has great inertia. The flywheel outer loop passes through locating hole fixed connection with the ring gear, has avoided the ring gear to drop long service life from the flywheel outer loop.
Description
Technical field
The utility model relates to a kind of mechanical parts, is specifically related to a kind of flywheel.
Background technique
Flywheel is mounted in the colyliform accumulator had compared with large rotating inertia on machine turning axle.When machine rotational speed increases, the kinetic energy of flywheel increases, and energy storage or saving is got up; When machine rotational speed reduces, flywheel energy reduces, fault offset out.Flywheel can be used for reducing the speed fluctuation of mechanical operation process, and the more important of the quality of flywheel design is whether the rotary inertia of flywheel is enough large.
In addition, flywheel is a castiron flying wheel, and its function is stored up a part for the energy produced during motor expansion stroke, in order to overcome the resistance of other auxiliary stroke, make bent axle Rotating with Uniform, and improve the overload capacity that motor overcomes short-term, vehicle is easily started to walk.Flywheel is made up of Flywheel disc and the gear ring be arranged on outside Flywheel disc, when the engine is started, the starting tooth of gear ring and motor can produce vibration in engagement process, in the course of time, will rub between Flywheel disc and gear ring and produce gap, gear ring can be caused time serious to come off, damage other component, shorten the working life of flywheel.
Model utility content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provide a kind of gear ring can be avoided to loosen or come off, flywheel that rotary inertia is large.
For this reason, the utility model provides a kind of flywheel, comprises flywheel body, the gear ring that described flywheel body comprises flywheel inner ring, flywheel outer shroud and is arranged on outside flywheel outer shroud; Described flywheel inner ring is connected by connecting rod with flywheel outer shroud, and the central position of described flywheel inner ring is provided with bearing hole; What described flywheel outer shroud connected with gear ring is circumferentially provided with positioning pin hole, and described positioning pin hole comprises the first half pin-and-holes that are arranged on flywheel outer shroud and the second half pin-and-holes be arranged on gear ring.
As structural improvement, described flywheel inner ring is provided with positioning hole.
As structural improvement, the thickness of described connecting rod and flywheel inner ring is the 1/3-2/3 of the outer ring thickness of flywheel.The Thickness Ratio flywheel outer shroud of flywheel inner ring and connecting rod is little, so just makes the rotating spindle of mass distribution away from flywheel of flywheel, thus improves the rotary inertia of flywheel.
As preferably, the thickness of described connecting rod and flywheel inner ring is 1/2 of the outer ring thickness of flywheel.This Thickness Ratio, the rotary inertia of flywheel is better.
As preferably, described positioning pin hole has two, and is symmetrical arranged relative to the central position of flywheel outer shroud.
The beneficial effects of the utility model: this flywheel that the utility model provides, structure is simple, due to the outside of the mass distribution deflection flywheel body of flywheel body, makes flywheel main body have larger rotary inertia.Flywheel outer shroud is fixedly connected with by positioning pin hole with gear ring, avoids gear ring and comes off from flywheel outer shroud, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1, flywheel body; 2, gear ring; 3, flywheel outer shroud; 4, connecting rod; 5, flywheel inner ring; 6, positioning hole; 7, positioning pin hole; 8, bearing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
Embodiment:
The utility model provides a kind of flywheel, as shown in Figure 1, comprises flywheel body 1, the gear ring 2 that shown flywheel body 1 comprises flywheel inner ring 5, flywheel outer shroud 3 and is arranged on outside flywheel outer shroud 3; Described flywheel inner ring 5 is connected by connecting rod 4 with flywheel outer shroud 3, and the central position of described flywheel inner ring 5 is provided with bearing hole 8; What described flywheel outer shroud 3 connected with gear ring 2 is circumferentially provided with positioning pin hole 7, and described positioning pin hole 7 comprises the first half pin-and-holes that are arranged on flywheel outer shroud 3 and the second half pin-and-holes be arranged on gear ring 2.Described positioning pin hole 7 has two, and is symmetrical arranged relative to the central position of flywheel outer shroud 3.Flywheel outer shroud 3 is fixedly connected with by two positioning pin holes 7 with gear ring 2, avoids gear ring 2 to come off through rubbing for a long time.The working life of flywheel is lengthened.Described flywheel inner ring 5 is provided with positioning hole 6.
The thickness of described connecting rod 4 and flywheel inner ring 5 is the 1/3-2/3 of flywheel outer shroud 3 thickness.The Thickness Ratio flywheel outer shroud 3 of flywheel inner ring 5 and connecting rod 4 is little, so just makes the rotating spindle of mass distribution away from flywheel of flywheel, thus improves the rotary inertia of flywheel.
The thickness of described connecting rod 4 and flywheel inner ring 5 is 1/2 of flywheel outer shroud 3 thickness.This Thickness Ratio, the rotary inertia of flywheel is better.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
